•
When the Vt Target is OFF, the delivered PI is the set PI. The mode is then equivalent to
PCV mode.
•
If the Vt Target is disabled during ventilation, the set pressure takes the current regulation
value.
The PI value corresponds to the pressure added to the current PEEP value. The pressure applied to the
patient is then equal to PI + PEEP.
Whatever the circumstances, the delivered PI should never exceed the PI Max.
CAUTION:
The “Vt target and regulated pressure incompatibility!!!” alarm is activated when:
•
Monitored volume < 90% of the Vt Target and delivered PI = PI Max;
•
Monitored volume > 110% of the Vt Target and delivered PI = PEEP + 5 cmH2O.
Furthermore if the Ppeak, Vti Max or patient disconnection alarm is set off, the adaptation of
the PI is inhibited until the alarm stops.
Ventilation set-points
FiO2
inspired oxygen fraction (%)
Vt Target
volume target (mL);
RR
minimum respiratory frequency (c/min);
PEEP
positive end of expiration pressure (cmH2O);
TI/Ttot
ratio of inspiration time to total cycle time (%);
PI
inspiratory pressure (cmH2O);
PI max
maximum inspiratory pressure (cmH2O);
I.Trig
inspiratory trigger (L/min or cmH2O);
Slope
inspiratory pressure slope (cmH2O/s);
CAUTION:
The Vt Target should not be used in NIV. If there is a leak, the tidal volume moni-
tored by the ventilator no longer represents the tidal volume inhaled by the patient. Any adap-
tation of the pressure is therefore inappropriate.
4.7.11 PS – PRO (interlocked barometric mode, intended for use in resuscitation)
Principle
The PS Pro mode is a PSV type pressure-regulated ventilation whose assistance frequency evolves au-
tomatically between two set frequencies: RR min and RR support (minimum frequency and maintained
frequency).
The aim of automatic adaptation of the frequency is to let the patient breathe autonomously when his
or her respiratory reflexes are active and allow the ventilator to take over when his or reflexes are inac-
tive.
Furthermore, the PS Pro mode can be combined with the Vt Target function. The inspiratory assis-
tance pressure is then adapted, cycle to cycle, so that the monitored Vt may converge towards the set
Vt Target.
If the patient spontaneously triggers above RR mini, each patient effort will be assisted. The set fre-
quency will then be the frequency of the patient.
